Impact of Letermovir for Cytomegalovirus Primary Prophylaxis on Myelosuppression and Immunosuppression in Lung Transplant Recipients.

Background: Cytomegalovirus (CMV) is associated with detrimental outcomes after lung transplantation (LTX); primary prophylaxis (PPX) with valganciclovir (VGC) is guideline-recommended. VGC is associated with myelosuppression, spurring interest in letermovir (LTV).

Methods: Adults undergoing LTX between January 1, 2021, and July 30, 2022 at our institution who were converted from VGC to LTV for PPX were evaluated.

Use of letermovir for cytomegalovirus primary prophylaxis in lung transplant recipients.

Background: Cytomegalovirus (CMV) is a driver of negative outcomes after lung transplant (LTX) and primary prophylaxis (PPX) with valganciclovir (VGC) is standard-of-care. VGC is associated with myelosuppression, prompting interest in letermovir (LTV).

Methods: Adults receiving LTX between April 1, 2015, and July 30, 2022, at our institution were evaluated.
